                        透水混泥土

                        概覽
                        • 透水混凝土又稱多孔混凝土,無砂混凝土,透水地坪,其是由骨料、水泥和水拌制而成的一種多孔輕質混凝土,它不含細骨料, 由粗骨料表面包覆一薄層水泥漿相互粘結而形成孔穴均勻分布的蜂窩狀結構, 故具有透氣、透水、重量輕高散熱的特點,也可稱無砂混凝土。其由歐美、日本等國家針對原城市道路的路面的缺陷,開發使用的一種能讓雨水流入地下,有效補充地下水,緩解城市的地下水位急劇下降等等的一些城市環境問題。并能有效的消除地面上的油類化合物等對環境污染的危害;同時,是保護地下水、維護生態平衡、緩解城市熱島效應、促進地表水循環的優良的鋪裝材料;其有利于人類生存環境的良性發展及城市雨水管理與水污染防治,改善城市發展次生環境問題等工作上,具有特殊的重要意義。

                        • 透水彩色路面的六大優勢
                        • 增加城市可透水、透氣面積,加強地表與空氣的熱量和水分交換,調節城市氣候,降低地表溫度,有利于緩解城市“熱島現象”;
                        • 充分利用雨、雪降水,增大地表相對濕度,補充城區日益枯竭的地下水資源,發揮透水性路基的“蓄水池”功能,改善城市地表植物和土壤微生物的生存條件和調整生態平衡;
                        • 能夠減輕降雨季節城市道路排水系統的負擔,明顯降低暴雨對城市水體的污染;
                        • 吸收車輛行駛時產生的噪音,創造安靜舒適的生活和交通環境;
                        • 防止路面積水和夜間路面反光,冬天不會在路面形成黑冰(由霜、霧形成的一層幾乎看不見的薄冰,極危險),提高了車輛、行人的通行安全性和舒適性;
                        • 大量的空隙能吸附城市污染物粉塵,減少揚塵污染;
                        規格名稱

                        Free Tab : Each product can have one to four tabs with any information of choice. They are called Free Tabs. The moment one or more Free Tabs are used the complete single product page changes to a tabbed layout.

                        1) The normal product information content goes into a tab called 'General Details',
                        2) The Attachments go into a tab called 'Attachments',
                        3) The Related Products go into a Tab called 'Related Products'
                        4) The Comments go into a tab called 'Comments'.

                        The Free Tabs are also added. Each one shown with its own title and content as set below in the free tab settings.

                        The titles of the default product tabs (not the free tabs) can be changed by the use of the default language file that comes with the theme and a program called PoEdit. This is called localizing the theme. Even if your native language is English you can create your own language file and change the wording used in the tabs. Follow the wordpress codex on this on the how to localize your theme. You can change/translated any text string used in the frontend of your website. All the frontend website strings are available for translation in the default language file which is included in the package and which can be found in the RtThemeXX/languages folder.
